Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, the structure schematic diagram of the oil pumping unit utilizing the power assembly to carry out the counterweight of the present invention is provided, which consists of a support 1, a beam 2, a counterweight donkey head 3, a fixing member 4 and a mechanism for driving the beam to reciprocate up and down. The driving mechanism consists of the middle part of the beam 2 shown hinged on the top of the bracket 1, the counterweight donkey head 3 fixed on the left end of the beam 2, and the fixing part 4 fixed on the right end of the beam 2. The sucker rod 5 is arranged on the fixing member 4 for realizing the oil pumping operation, and the driving mechanism is arranged at one end of the counterweight donkey head.

[0019] The driving mechanism shown is composed of an outer frame 7, an inner frame 8 and a power assembly 9,...

Abstract

The invention discloses a pumping unit using a power assembly for counterweight. The pumping unit comprises a support, a walking beam, a counterweight horse head, a fixture and a driving mechanism. The pumping unit is characterized in that the driving mechanism comprises an outer frame, an inner frame and the power assembly, side rollers are arranged on the inner frame, vertical slides matched with the side rollers are arranged on the inner wall of the outer frame, a plurality of bottom rollers are arranged at the bottom of the power assembly, horizontal slides matched with the bottom rollers are arranged on the inner frame, a gear is fixed onto an output shaft, a double-faced rack engaged with the gear is fixed onto the outer frame, a limit ring is arranged on one side of the center of the double-faced rack, and a limit roller matched with the limit ring is fixed onto the output shaft. The walking-beam pumping unit uses the power assembly for counterweight, the weight of an original pumping unit is greatly reduced, raw materials are saved, manufacturing cost is reduced, transportation, installation and maintenance are facilitated, and the pumping unit has remarkable advantages and is suitable for application and popularization.

Description

technical field [0001] The invention relates to a beam pumping unit, more specifically, to a pumping unit using a power assembly as a counterweight. Background technique [0002] The beam pumping unit is an effective oil production tool in the oil field. The power assembly outputs power, and the transmission mechanism drives the beam to reciprocate up and down, and the oil pumping operation is completed by the sucker rod at the end of the beam. During the oil pumping process, in order to realize the weight balance at both ends of the beam, it is necessary to set a counterweight donkey head at one end of the beam to ensure the stability of the pumping unit during work. [0003] Due to the use of counterweights, the weight of the whole beam pumping unit is very large, which not only makes transportation, installation and maintenance difficult, but also increases the manufacturing cost of the whole pumping unit. The powertrain is a necessary equipment of the pumping unit, and ...
